18 is the legal age. if you are 16, then you need both of your parents with you to sign a consent form. if the shop doesn’t do it that way, or is dirty, run. i think that if you waited 6 yrs, then you can wait 2 more. the tat is a good thought, if that’s the one you want, but make sure you won’t regret it.

8 inches is NOT a SMALL tattoo! if it’s that big, then it’ll take one to two hours, depending on the detail involved. if you mean SMALL, then maybe 45 minutes. it’s painful. needles are going in and out of your skin, so it won’t tickle.
